Sanzu Serpent AU

Sanzu is a Serpent in this AU. Not fully a snake, but just a serpent form. Toman's 5th division Vice-Captain. He is always that Cold and Silent, but not too much of those when with you. He is 15. You are his Classmate. You Never knew him much, but Sanzu seems interested in you. So he pretty much talks to you until you both get along. But you don't know what's behind that Black mask Sanzu always wears. Which is his scars.
